Abstract
It the utility model is related to technical field of aircraft structure design, specifically provide a kind of pump nozzle attachment structure of aircraft structure, structural member is provided with unthreaded hole, the unthreaded hole is built with connector and pump nozzle, connector is cylindrical, and it is interference fitted with the unthreaded hole, and connector inwall is provided with screw thread, pump nozzle is mutually fixed by the screw thread with connector, and the material of connector is polytetrafluoroethylene (PTFE);The pump nozzle attachment structure of the aircraft structure increases a connection piece as transition piece between pump nozzle and structural member, avoids the form that screw thread is directly processed on structural member, protects structural member not by breakage, and greatly increase the service life of structural member.
Description
Technical field
It the utility model is related to the pump nozzle connection knot of technical field of aircraft structure design, more particularly to aircraft structure
Structure.
Background technology
It is threaded connection because the pump nozzle largely used at present is connected with structural member, therefore pump nozzle is installed,
Just screw thread need to be processed in advance on structural member, then be installed, but due to processing screw thread on structural member to structural member
Service life has an impact.
Utility model content
The defects of to overcome above-mentioned prior art to exist, the pump nozzle that the utility model provides a kind of aircraft structure connect
Binding structure.The pump nozzle attachment structure of aircraft structure, structural member are provided with unthreaded hole, and the unthreaded hole is built with connector and oiling
Mouth, connector is cylindrical, and it is interference fitted with the unthreaded hole, and connector inwall is provided with screw thread, and pump nozzle passes through the screw thread
Mutually fixed with connector.
Preferably, the material of connector is polytetrafluoroethylene (PTFE).
The pump nozzle attachment structure of aircraft structure provided by the utility model increases by one between pump nozzle and structural member
Connector avoids on structural member the directly form of processing screw thread, protects structural member not by breakage as transition piece, and greatly
The service life of big increase structural member.
Brief description of the drawings
Fig. 1 is the component diagram of the pump nozzle attachment structure of aircraft structure;
Fig. 2 is the overall schematic of the pump nozzle attachment structure of aircraft structure.
Reference:Pump nozzle 1, connector 2, structural member 3.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is the utility model part of the embodiment to apply example, rather than whole embodiments.Below with reference to the embodiment of accompanying drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
The utility model is described in further detail below by specific embodiment.
Specific embodiment:
The utility model provides a kind of pump nozzle attachment structure of aircraft structure, and structural member 3 is provided with unthreaded hole, described
Unthreaded hole is built with connector 2 and pump nozzle 1, and connector 2 is cylindrical, and it is interference fitted with the unthreaded hole, in the present embodiment, even
The material of fitting 2 is polytetrafluoroethylene (PTFE), the material corrosion-and high-temp-resistant and coefficient of friction is low;The inwall of connector 2 is provided with screw thread, note
Oil nozzle 1 is fixed by the screw thread and the phase of connector 2, makes its lubrication to oiling in structural member 3 by pump nozzle 1.
When installing the pump nozzle attachment structure, the connector 2 processed is installed into knot by the form for first passing through interference fit
Connector 2 is screwed into the unthreaded hole of component and then by pump nozzle 1, this structure type avoids directly processes screw thread on structural member 3
Form, protect structural member 3 not by breakage, and greatly increase the service life of structural member 3.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
Scope of the claims is defined.
